Even the Bieber doesn’t like Tom Brady’s hair.

Tom Brady, Superbowl-winning quarterback and husband of a supermodel, ought to be the idol of the male masses.

Instead, everyone is making fun of his hair. Now Justin Bieber — he of the hair that can come only from clamping a bowl on your head and getting out the clippers — is jumping on him. And the kid is a Canadian to boot!

We’re talking a place where they punt on third down. Stick that in your Grey Cup and take a drink.

In a new video the tweener sensation raps: “Sacked like a sacker. Call up Mr. Brady. Tell him to leave his hair to the guy who sings ‘Baby.’”

We think Master Justin ought to stick to curling — the game, not his hair.
